I will explain the new habbo packet handling
What's the difference?
- No base encoding anymore. They using Bits.
How to handle an Integer?
Get 4 Numbers (as bits).
Bits explaining
Every single item stands for an integer of an max of (255).Code:Example: 1-0-0-0 = 1 as int 0-1-0-0 = 256 as int 1-1-0-0 = 257 as int (1x 256 + 1) 1-2-0-0 = 513 as int (2x 256 + 1) You have to count further. Like having 4 Row(s) in an byte array. Every row has an max of 255 (bit). 1-2-3-4 Rows. If the row has reaches his max then the next row gets + 1. Thent he old row will be set to 0, to count again.
Int lengths
Int32 = 4 (bits)
Int16(short) = 2 (bits) [Used for HeaderId and string lengths]
Something weird
Habbo reversed the bytes sometimes.
Boolean explaining
They just used a single bit for the boolean.
String explainingCode:Example True = 1 False = 0
Not that hard, they just used as first.
[String Length (as short)] + Text of string.
Characters explaining
Just use your bitconverter to do this.
With all pleasure :)
Like if you know more after reading this!
New ServerMessage
Code:using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace HabboTCP.Messages.Library { class ServerMessage { private List<byte> Context = new List<byte>(); public ServerMessage(short HeaderId) { Append(HeaderId); } public void Append(object Item) { if (Item is Int32 || Item is int) { AddInt32((Int32)Item); } else if (Item is Int16 || Item is short) { AddInt16((Int16)Item); } else if (Item is Boolean || Item is bool) { AddBoolean((Boolean)Item); } else if (Item is String || Item is string) { AddString(Item as string); } } private void AddInt32(Int32 Item) { AddBytes(BitConverter.GetBytes(Item), ReverseType.Reversed); } private void AddInt16(Int16 Item) { AddBytes(BitConverter.GetBytes(Item), ReverseType.Reversed); } private void AddBoolean(Boolean Item) { AddBytes(new byte[] { (byte)(Item ? 1 : 0) }, ReverseType.Fresh); } private void AddString(String Item) { AddInt16((short)Item.Length); AddBytes(Encoding.ASCII.GetBytes(Item), ReverseType.Fresh); } private void AddBytes(byte[] Bytes, ReverseType Type) { if (Type == ReverseType.Reversed) { for (int i = (Bytes.Length - 1); i > -1; i--) { Context.Add(Bytes[i]); } } else { Context.AddRange(Bytes); } } public byte[] Bytes() { var Result = new List<byte>(); Result.AddRange(BitConverter.GetBytes(Context.Count)); Result.Reverse(); Result.AddRange(Context); return Result.ToArray(); } } enum ReverseType { Fresh, Reversed } }
